Looking for a manga

I saw it in an ad briefly and didn't catch the title. The few panels I saw were a female character running a territory in a medieval setting while her husband was at war. She sent him a letter about getting a divorce. He said something to his friend like "it looks like my wife wants me dead"(?) then he got mad and was heading back home since the war ended. I'm not sure if it's enemies to lovers but for sure rofan arranged marriage in a medieval aesthetic. I *think* the fmc might have been blonde but I'm not 100%.
